COWL.

Specification of Letters Patent.

Application filed June 24, 1907.

Patented June 30, 1908.

Serial No. 380,480.

To all whom it may concern:

Be it known that I, O'rro SCHUBERT, a subject of the King of Prussia,and a resident of Charlottenburg, near Berlin, in the Kingdom of Prussiaand German Empire, have invented new and useful Improvements in Cowls,of which the following is a specification.

My invention relates to an improved chimney top or cowl, comprising twosuperposed tubular sections united by a ball and socket joint, so thatthe upper section can adjust itself according to the direction of thewind.

The invention is illustrated in the accompanying drawing, in whichFigure l is a vertical section through a cowl, Fig. 2 a vertical sectionthrou h the top cowl pipe, and Fi 3 a sectiona view showing to a largerscje a detail to be hereinafter referred to. Fig. 4 is an elevation ofthe cowl.

The cowl consists of two main parts: the fixed pipe A and the movablepipe B superposed thereon. The top of the pipe A has the form of atruncated sphere a, which is received by the foot of the pipe B, whichhas somewhat the shape of an inverted cup I). The two arts 0. and I)thus constitute a socalled bal and socket joint. The ball a contains a sider or the like h, supporting a hardened stee boss g, presenting apoint exactly in the center of the ball a. The pipe B contains a spideror the like (I at whose center there is secured a dependent rod 0. Theend of the rod is hardened and presents a recess to receive the point ofthe boss g, on which it rests. At the bottom of the rod 0 there issecured an annular cross c, with pendent balance-weight.

It is obvious that owing to the ball and socket joint the section B willyield to the force of the Wind and bend over more or less in thedirection of the latter, as indicated by dotted lines in Fig. 1. Onabatement of the wind the weight fwill return the section B to itsnormal upright position (Fig. l).

WVhatever position the section B may occupy, it is clear that the smokefrom the chimney will always pass from the pipe A through the pipe B.

Having thus described my invention, I claim as new:-

1. A cowl comprising two superposed tubular sections in which the top ofthe lower section has the "form of a truncated sphere, which is embracedby the cupped foot of the upper section, the lower section having adevice presenting a central bearing point on which the upper sectionrests by means of a rod connected therewith substantially as described.

2. A cowl, comprising a lower tubular section whose top has the form ofa truncated sphere; a device presenting a central bearing oint securedin this section; an upper tubuar section having a cupped foot whichenibraees the top of the lower section; and a member secured centrallyin the upper sec tion and resting upon said point; substantially asdescribed.

3. A cowl, comprising a lower tubular section whose top has the form ofa truncated sphere; a device presenting a central bearing oint securedin this section; an upper tubuar section having a cupped foot whichembraces the top of the lower section; a pendent member securedcentrally in the upper section and resting upon said point; and abalance-weight attached to said pendent member; substantially asdescribed.

In testimony whereof I aflix my signature in presence of two witnesses.

OTTO SCHUBERT.
